Faucets are closely related items in our lives. Most people should have had the experience of buying faucets. We often hear that 25 yuan/stainless steel faucet buys home, 10 yuan/stainless steel faucet sale, 200 yuan/each Stainless steel faucet... The same is a stainless steel faucet, the price is actually from a few to a few hundred, which has turned hundreds of times. Are you lost? Today we will reveal the manufacturing process of the secret faucet.
Classification of raw materials for faucets: The common raw materials for faucets on the market are: stainless steel, all-plastic, brass, zinc alloy data faucets and other categories.
1. Brass: Brass is the most widely used data for faucet manufacturing. It is made of H59/H62 copper in international specifications. Casting uses steel molds for gravity casting. Its wall thickness is uniform, generally 2.5-3.0 mm. The characteristics of the faucet made of brass are: no rust, used, anti-oxidation, sterilizing effect on water (the disadvantage is: lead, lead is a metal that is harmful to health, international regulations require that lead in copper content must not Over 2.5%.
2. Zinc alloy: low-level data, the density of zinc alloy is smaller than that of copper, and the tap without copper feels heavier. From the inner wall, the appearance of zinc alloy is very oxidized, and white oxide powder will appear on the surface. The strength is much worse than copper, the service life is not long, and the lead content is high. If the faucet made of zinc alloy will oxidize and rot in only one to two years. Now zinc alloy is mainly used to make the handle of faucet. It is made of zinc alloy die-casting and then chrome plated. Most faucet handles on the market are made of zinc alloy.
3. Engineering plastics: ABS plastic faucet has the characteristics of corrosion resistance, aging resistance, no rust, no lead, no poison, no taste, high pressure resistance, light weight, simple construction, low price, etc. It is a new type of green environmental protection type The product makes the water quality free from the risk of corrosion and pollution; the faucet made of plastic is environmentally friendly, non-toxic, non-polluting, compact in shape, simple and convenient to install, and meets the national drinking and civil drinking water standards. This green and environmentally friendly product will be a boost in the faucet industry and should be promoted vigorously.
4. Stainless steel: In the 21st century, health and environmental protection have gradually become the new theme of modern life. Stainless steel is an internationally recognized healthy raw material that can be implanted into the human body. Therefore, kitchen and bathroom supplies that use stainless steel as the primary raw material have begun to become popular in European and American countries. However, due to the characteristics of high hardness and strong resistance of stainless steel raw materials, it is difficult to manufacture and process, which seriously affects the mass production of stainless steel faucets. Therefore, the real 304 stainless steel faucet price is higher than the price of copper. Its characteristics are: health and environmental protection; all the raw materials of the product are made of high-quality 304 stainless steel, which is not rusty and lead-free. The faucet itself will not cause secondary lead pollution to the water source, harming people's health, and can invent a healthy kitchen for us Health water environment.
